Study Notes
Anatomy and Physiology Terms
- Tissues are groups of cells with similar structures and functions.
- Epithelial tissue forms boundaries and covers the body. It's categorized by the number of cell layers and cell shapes.
- Connective tissue supports, protects, and binds. It's made of fibers and gels. Examples include bone and blood.
- Neural tissue facilitates communication. Neurons and supporting cells transmit signals.
- Muscle tissue controls movement, including smooth muscle lining organs.
Axial Skeleton
- The axial skeleton includes bones like the clavicle, ribs, sternum, and vertebral column sections (cervical, thoracic, lumbar, sacral, coccygeal).
Anatomical Position
- Anatomical position: Upright, facing forward, feet shoulder-width apart, palms forward.
- Medial/Lateral refers to relative positions, e.g., nose is medial to the eyes.
- Sagittal plane is a vertical cut dividing body in half.
Planes of the Body
- Planes of the body are imaginary or real cuts through the body (based in anatomical position) including medial, lateral, sagittal, coronal, and transverse.
Respiratory System (Upper)
- The nasal cavity warms, humidifies, and filters inhaled air with cilia and mucosa.
- Nasal conchae in the cavity increase the turbulence for filtering.
- The oral cavity is an alternate route for airflow during heavy breathing.
- The pharynx connects the nasal and oral cavities to the larynx, and includes the nasopharynx, oropharynx, and laryngopharynx.
- The pharynx plays a role in voice resonance.
Respiratory System (Lower)
- The trachea, often called the windpipe, is supported by C-shaped cartilage rings.
- The trachea branches into two bronchi.
- The bronchi branch into smaller bronchioles.
- Bronchioles end in alveoli for gas exchange.
- Alveoli are tiny balloon-like structures where gas exchange happens.
Skeletal Framework of Respiration
- Vertebral column: Composed of vertebrae (cervical, thoracic, lumbar, sacral, coccygeal) and provides support.
- Ribcage: Made of ribs, sternum, and cartilage. Protects organs. Provides space and structure for respiration, as they expand during breathing.
- Shoulder (pectoral) girdle: Important connection point for muscles involved in inhaling.
- Pelvic girdle: Supports abdominal and lower back muscles involved in respiration.
Lungs
- The right lung is divided into three lobes; left into two.
- Lobes are separated by fissures (grooves).
- Function of lungs is in gaseous exchange and maintaining lung function.
Passive and Active Forces of Respiration
- Passive forces (in relaxed breathing): recoil of tissues, and gravity.
- Active forces (in forceful breathing): involve muscle contractions like the diaphragm and intercostal muscles, adjusting lung volume/pressure.
Neural Control of Tidal Breathing
- Brainstem, specifically the medulla, controls automatic, basic breathing patterns.
Posture and Body Position
- Posture and position affect respiratory efficiency. Different positions demand varying muscular support.
- Upright position: diaphragm and rib cage expand easily.
- Lying down: Expands rib cage with more work.
Aging and Respiration
- Lung capacity and function can decrease with age: alveoli, diaphragm strength.
- Aging also affects nerve sensitivity and the ribcage structure which affects respiration and consequently speech.
